Objective: : We performed an expanded multi-ethnic meta-analysis to identify associations between inflammation-related loci with intracranial aneurysm (IA) susceptibility. This meta-analysis possesses increased statistical power as it is based on the most data ever evaluated. Methods: : We searched and reviewed relevant literature through electronic search engines up to August 2022. Overall estimates were calculated under the fixed- or random-effect models using pooled odds ratio (OR) and 95% confidence intervals (CIs). Subgroup analyses were performed according to ethnicity. Results: : Our meta-analysis enrolled 15 studies and involved 3070 patients and 5528 controls including European, Asian, Hispanic, and mixed ethnic populations. Of 17 inflammation-related variants, the rs1800796 locus (interleukin [IL]-6) showed the most significant genome-wide association with IA in East-Asian populations, including 1276 IA patients and 1322 controls (OR, 0.65; 95% CI, 0.56–0.75; p=3.24×10-9) under a fixed-effect model. However, this association was not observed in the European population (OR, 1.09; 95% CI, 0.80–1.47; p=0.5929). Three other variants, rs16944 (IL-1β), rs2195940 (IL-12B), and rs1800629 (tumor necrosis factor-α) showed a statistically nominal association with IA in both the overall, as well as East-Asian populations (0.01
Conclusion
: Our updated meta-analysis with increased statistical power highlights that rs1800796 which maps on the IL-6 gene is associated with IA, and in particular confers a protective effect against occurrence of IA in the East-Asian population.

BACKGROUND/AIMS: Acute gastric injury by alcohol or indomethacin has been reported to be prevented by DA-9601, an extract of the herb Artemisia asiatica. Ghrelin, an endogenously produced gastrointestinal peptide hormone, has also been demonstrated to play a role in gastric mucosal defense. The aim of this study was to investigate the effects of DA-9601 on ghrelin in an acute gastric injury model induced by alcohol or indomethacin. METHODS: A total of 140 Sprague-Dawley rats were divided into two groups, a placebo group and a DA-9601-pretreated group. Thirty minutes later, half of the rats in each group received ethanol injury and the other half received indomethacin injury. Levels of serum ghrelin and gastric mucosal ghrelin mRNA were measured by ELISA and RT-PCR, respectively. RESULTS: Immediately after ethanol administration, ghrelin increased in both groups pretreated with DA-9601 and placebo. However, the increase occurred more rapidly and was higher in the DA-9601-pretreated rats than in the controls that did not receive DA-9601-pretreatment. Similarly, from 30 minutes to 2 hours after indomethacin administration, the DA-9601-pretreated rats showed a significant increase in serum and gastric mucosal ghrelin concentrations, whereas placebo-pretreated rats showed only a mild increase. CONCLUSIONS: DA-9601 potentiates the endogenous production and secretion of ghrelin in acute gastric injury models induced by ethanol or indomethacin.

PURPOSE: To evaluate the incidence and clinical features of age-related macular degeneration (AMD) in Korea. METHODS: Web-based (www.armd-nova.or.kr) registration was conducted for AMD patients aged 50 or more who were newly diagnosed by retinal specialists in Korea from August 20, 2005 to August 20, 2006. Patient data including ophthalmologic examination, fundus photography, fluorescein angiogram and/or indocyanin green angiogram (ICG), past medical history, behavioral habit, combined systemic diseases were up-loaded. RESULTS: Among finally enrolled 1,141 newly diagnosed AMD patients, 690 patients (60.5%) were male and 451 patients (39.5%) were female. The average age of AMD patients was 69.7+/-8.0. Early AMD was observed in 190 patients and 951 patients had late AMD. Classic choroidal neovascular membrane (CNVM) was observed in 18.6% of exudative AMD patients and 63.4 % had occult CNVM. Subfoveal CNVM was observed in 80.4% of the patients with CNVM. Among the 580 exudative AMD eyes that performed indocyanin green angiography (ICG), 184 eyes (31.7%) had polypoidal choroidal vasculopathy (PCV) and 36 eyes (6.2%) showed retinal angiomatous proliferation (RAP). Age, male gender, smoking, diabetes and hypertension significantly increased the risk of the AMD among Koreans. CONCLUSIONS: Because of the low rate of participation by retinal specialists, definite incidence of AMD was not obtainable. However, the estimated 1-year AMD incidence in the Pusan area of Korea is at least 0.4%. In contrast to Western people, 31.7% of exudative AMD cases were revealed to be PCV and 6.2% were revealed to be RAP. This discrepancy between ethnic groups should be considered in the diagnosis and treatment modality selection of Korean AMD patients.

PURPOSE: To prospectively investigate the change of clinical manifestations after 1 year of administration of anthocyanoside (Tagen-F(R)) to patients with NPDR-associated macular edema. METHODS: One hundred seventy-five eyes in 88 patients were enrolled in this study, at 5 centers, from March, 2005 to October, 2005. Patients took 3 capsules of Vaccinium myrtillus extract (170 mg/capsule, Tagen-F(R), Kukje pharmaceutical) per day. The primary endpoints were corrected visual acuity and contrast sensitivity which were checked at 2 months following the beginning of treatment [East 1]. The secondary endpoints were the number of hard exudates, microaneurysms, leaking points and the changes of foveal thickness. These were examined at the beginning of, 6 months after, and 12 months after treatment. RESULTS: Corrected visual acuity showed no significant changes during 12 months. Contrast sensitivity improved gradually, especially in 12, 16 cycles per degree [East 2]. There was no statistically significant changes in the numbers of hard exudates, microaneurysms, and leaking points. Foveal thickness measured by OCT was maintained and there was no aggravation of macular edema. CONCLUSIONS: There was marked improvement of contrast sensitivity in patients with NPDR after 1 year of administration of anthocyanoside (Tagen-F(R)), and it might contribute to the quality of vision and the satisfaction of patients. Visual acuity and macular edema were maintained without aggravation.

Genital HPV infection is the most common sexually transmitted infection, but the majority of infections are self-limited. However, persistent infection with high-risk types can cause cervical cancer in women, which is the most common female genital cancer in Korea. In addition, HPV infection is the cause of genital warts and is associated with other anogenital cancers. The HPV vaccine is composed of the HPV L1 protein, the major capsid protein of HPV. Expression of the L1 protein in yeast using recombinant DNA technology produces noninfectious virus-like particles (VLP) that resemble HPV virions. The quadrivalent HPV vaccine is a mixture of four HPV type-specific VLPs prepared from the L1 proteins of HPV 6, 11, 16, and 18 combined with an aluminum adjuvant. Clinical trials indicate that the vaccine has high efficacy in preventing persistent HPV infection, cervical cancer precursor lesions, vaginal and vulvar cancer precursor lesions, and genital warts caused by HPV types 6, 11, 16, or 18 among females who have not already been infected with the respective HPV type. The recommended age for primary vaccination of Korean females is 15-17 years, considering sexual debut and duration of protection of the vaccine. Vaccine can be administered as young as age 9 years. Catch-up vaccination is recommended for females aged 18-26 years who have not been previously vaccinated. Vaccination is not a substitute for routine cervical cancer screening, and vaccinated females should have cervical cancer screening as recommended.

Appendiceal mucocele is a cystic dilatation of the appendiceal lumen with mucus, which may be caused by either benign or malignant diseases. In this report, five cases of appendiceal mucocele are reported, three of which had a preoperative diagnosis of mucocele, whereas the others were found incidentally during the operation under the diagnosis of intussusception and periappendiceal abscess. All five patients underwent surgical resections, including one ileocecal resection and four right hemicolectomies. Histopathology revealed a mucinous cystadenoma in four cases, and a mucinous cystadenocarcinoma in one. There was no disease-related death during 18 months of follow-up.

PURPOSE: To investigate the effects of repeated photodynamic therapy (PDT) for subfoveal choroidal neovascularization secondary to age-related macular degeneration (AMD) in Korean patients. METHODS: Clinical data of patients who were treated with repeated (3 times or more) PDT for subfoveal choroidal neovascularization secondary to AMD and followed up for more than 6 months were collected from 17 hospitals around the country. Visual outcomes at 12 and 24 months, follow-up were compared between subtypes of choroidal neovascularization. The factors related to final visual prognosis and PDT-related adverse effects were evaluated. RESULTS: 244 patients (244 eyes) were recruited (male: 60%, age: 67.7+/-9.1 years). The portion of patients with predominantly classic, minimally classic, and occult without classic choroidal neovascularization was 57%, 13%, and 24%, respectively and that of patients with visual improvements or less than moderate visual loss at 24 months follow-up were 28%, 38%, 30% and 47%, 56%, and 65%, respectively. Baseline visual acuity and age were significantly related to the final visual prognosis (p<0.05). PDT-related adverse events developed in 15 (6.1%) patients, but most were mild and transient. CONCLUSIONS: Repeated PDT for subfoveal choroidal neovascularization secondary to AMD has effects comparable to those of previous prospective, controlled trials without any significant safety concerns in Korea.

OBJECTIVE: The decision of optimal age for administration of recently approved prophylactic human papillomavirus (HPV) vaccines in the world depend on the basis of the sexual behavior of each countries. The aim of the study was to survey the age-specific sexual behavior including the sexual debut time and sexual experience in the Korean young women to design the tailored HPV vaccination. METHODS: This study was conducted by the Synovate Healthcare in the 6 city of Korea e.g. Seoul, Pusan, Daegu, Incheon, Kwangju and Daejon. By a stratified sampling methods 2,400 women aged 12-29 years old were included. The measures of sexual behavior presented in this report were collected by a Computer-Assisted Self-Interviewing (ACASI), in which the respondent enters her own answers into a computer without telling them to an interviewer. RESULTS: Among women 12-29 years of age, 39 percent of women (934 persons in 2,400 women) and 33 percent of single women (724 persons in 2,190 women) have had vaginal intercourse; 8 percent of women under 19 years old single women (79 persons in 1,045) and 56 percent of single women with 20-29 years old (645 persons in 1,145). Number of sexual partner was 2.8 person and 54 percent of women had more than 2 partners. Age of the first sexual activity (sexual debut) was 21 years old. The age of partner at the sexual debut was 23.2 years old. Sexual experience before 15 years old was only 2%. About the condom, 41% did not use or rarely use. CONCLUSION: Our data demonstrate that the sexual debut time of young Korean women differ from other countries in which the prophylactic HPV vaccine had already used. We conclude that the optimal age for HPV vaccination in Korea would be determined at 15-17 years old by this situation.

Nocardiosis is usually a subacute infection, which can occur as an opportunistic infections in patients with systemic lupus erythematosus. There are rare cases of nocardiosis concurrent with Mycobacterium tuberculosis. We report a case of intramuscular nocardial abscess concurrent with pulmonary tuberculosis in a patient with lupus nephritis. She has received cyclophosphamide pulse therapies and is receiving oral steroid therapy 3 months ago. After Nocardia farcinica and Mycobacterium tuberculosis were confirmed by PCR and PCR-RFLP, we initiated trimethoprim/ sulfamethoxazole and antituberculous agents. After then, patient was improved and discharged, maintaining the medications.

OBJECTIVE: Infliximab, a monoclonal antibody to tumor necrosis factor-alpha, is effective in patients with ankylosing spondylitis (AS), who have not responded to conventional therapy. There were no data on the efficacy and side effect of infliximab in patients with AS in Korea. The objective of this study is to observe the efficacy and adverse effect of infliximab retrospectively in Korean patients with AS. METHODS: We reviewed the medical records of thirty-three AS patients. The patients were enrolled to fulfill the modified New York criteria of AS and be in active disease state and resist to conventional therapy. Patients were given 3~5 mg/kg of infliximab infusions at weeks 0, 2, 8 and 16. Information on C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and antinuclear antibody (ANA) test was collected at each infusion. The paired t-test was used for comparison between the visits. RESULTS: There were 29 male and 4 female patients. The mean age at first infliximab treatment was 34.6+/-9.8 years. All patients were HLA-B27 positive. ESR and CRP decreased significantly from baseline to 16 weeks after treatment (p<0.001, respectively). The mean ESR was 76.1+/-36.5 mm/h at baseline and 21.3+/-31.6 mm/h at 16 weeks. The mean CRP was 6.4+/-4.8 mg/dL at baseline and 1.3+/-2.1 mg/dL at 16 weeks. Only 1 out of 33 patients got worse. All patients were tested negative for ANA at baseline. After 16 weeks of therapy, the induction of ANA was observed in 8 patients, but no patients have lupus-like symptoms. CONCLUSION: Infliximab is an effective therapy with non-specific adverse effect in AS non-responsive to conventional therapy in Korea.
